FRICTION-CLUTCH.

Specification of Letters Patent.

Application filed October 2, 1911.

Patented Aug. 13, 1912. Serial No. 652.318.

other mechanism, simple, cheap, easily managed means whereby power may be communicated from a suitable source to such mechanism without excessive shock or jar with consequent probable damage thereto. Thisobject I have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which:

Figure 1 is a front elevation of my improved friction clutch as operativcly conuectedto a driving-belt wheel. Fig. 2 is a vertical, axial transverse section of the parts shown in Fig. 1, taken along the line m of said Fig. 1.

Similar numerals of reference designate corresponding parts throughout the scvc :11 views.

lhe-numeral 12 designates the drivingshaft of any mechanism, such as that of n cei'itrifugal cream separator. while the numeral 10 designates a body having a socket adapted to receive the end of said shaft, and a set-screw 14 working in an expanded por- .tion 13 of said body acts to removably socure it upon said shaft. The body 10 has a projecting outwardly threaded screw 2' which is alined andcoaxial with said shaft, and upon which a cap-nut (3 is removably seated. On the cylindrical portion of said body 10 between the expansion 13 thereof and the said cap'nut 6, the hollow hubs 11 and 9 of the beltwvheel 1 and ot' the frictiondisk 5 are respectively seated, the belt-wheel being loose on said sleeve while the frictiondisk is secured to the sleeve by means of a cotter-pin 8 passed through registering grooves in said hub 9 and an orilicc in the solid portion of said sleeve lying between the end of said shaft and the screw (3. On that side of the spokes 2 of said belt-wheel 1 which faces the friction-disk 5 are located on several of said spokes in a desired nuruher, small projections or cylindrical studs blocks 3, and the rotation of said bclt-whcel 1 is not communicated to said disk. When, however, the nip-nut 6 is n'iovcd toward said friction-disk, the nut compresses the hub 9 causing the latter to s de over the pin 8 and forcing the frictionaiisk against the blocks 3 tightly enough to cause rotation to be comn'iunicatcd from said bclt-whccl to said disk and by consequence to the shaft 12. Since the hub S) is grooved to receive said pin 8, the operation is thus made possible. Since the separat'or-shat't 12 is to be rotated at a rate 0t only about 50 revolutions per minute, it is obviously safe to turn said cap-nut 6 by hand to release it from the hub 9, to disengage the belt-wheel from said shaft, and stop the latter, without stopping the driving-member.

Since the cap-nut is centrally located the operation above indicated may be quickly and easily performed, and the pressure of the friction-disk against said blocks be made so gradual that no shock or jar will be comniunicatcd to the shaft 12 and the mechanism driven thereby.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is:

1. In combination, a driven shaft, 11 driving-wheel loosely but non-slidably mounted thereon, a plurality of removable frictionblocks mounted on one side of said wheel, a friction-disk coaxial with said wheel and movable to and from it, and means for gradually advancing said disk into frictional contact with said friction-blocks 2. in combination, a driven shaft, a sleeve removably secured on one end thereof and provided with a. coaxial alined outwardly threaded projection and having a raised rin about its other end, a friction-disk slidlibly but non-rotatably mounted on said 4., spaced apart along the spokes, and which hub movably mounted on seated on said threaded adapted to bear graclually upon said disk to vcause the latter to gradually come into frictioial Contact with said f1'ictio1i-blocks.

3. In combination, a driven-shaft, a sleeve removably secured on one end thereof and provided "WltlLit coaxial alined outwardly threaded projection and having a fillet about its other end, a frictiomdisk rigid with a said-sleeve, said hub having its outer eiid diametricall grooved, said sleeve having a transverse orifioe in registration with said groove, a pin seated in saicl orifice and. groove, the said a art friction-blocks said frictiondisk and,

pm, a driving-Wheel loosely but non-sliclably mounted oii said sleeve lietween said fillet and said friction-disk, a plurality of spacedremovably mounted on met sMe of said wheel which is adjacent-t0 being equidistairit from the axis of said Wheel, and an adjustingmut movable on said projection and adapted to gradually force said frictiondisk' against said blocks.
